I wish I could play around with it a little bit. :D
Well, right now it *only* compiles on Linux <.< but it wouldn't be a far cry to get it working on Windows again, I just have to write another script for it.

I run Mac, Windows, and Linux.  So it really doesn't matter overall. :D

Or, instead of rewriting a script, you could use gcc thru cygwin and leave it as-is, right?

Doesn't matter much to me, since I use Linux pretty much exclusively.

How portable is the code to other z80s? Obviously, some RAM addressing would have to change, among other things, but it seems you could port the kernel, at least, to something like a Game Boy, or an Atari.

Game Boy wouldn't work, because it's not a fully-featured Z80. It's missing all ED-prefixed instructions, has no I/R/IX/IY/shadow registers, no sign/overflow flags, and some other instructions have been changed/removed.

Ok, so no Game Boy, but I was being theoretical anyways. :P I Don't have a GB Flash cart. They are expensive!

Well, technically it could be possible if KOS only used instructions compatible with both Z80 and GBZ80, but I don't think that would be very optimized, heh

Well, but it would port relatively easily to another fully-featured z80 CPU, like, say, the ez80, right?

Sure, since eZ80 has a mode for backwards-compatibility with Z80.

So, there's not tons of code related to specific hardware handling and such? That's what I was really wondering about :P Obviously there would be some, but too much is almost like rewriting it.

Oh yeah, that's true. That would pose a problem, especially for 3rd-party programs meant to run in the OS.
